Problem #5: Given the following five pairs of (x, y) values, Problem #5(a): Problem #5(b): x 2 3 11 7 14 y 9 8 5 30 (a) Determine the least squares regression line. (Be sure to save your unrounded values of bo and b₁ for use in Problem #6 below.) (b) Draw the least squares regression line accurately on a scatterplot. Then look to see which (x, y) pairs are above the regression line. Then add up the y-values for all of the (x, y) pairs that fall above the regression line. For example, if you draw your least squares regression line accurately on a scatterplot, and you find that the first two (x, y) pairs [i.e., (2,9) and (3,8)] are above the regression line, then since the sum of the two corresponding y-values is 9 + 8 = 17, you would enter 17 into the answer box. enter the values of bo and b₁ (in that order), separated by a comma (numbers correct to 4 decimals) sum of y-values for points above the regression line
